The population is all enterprises in the construction sector according to Standard Industrial Classification (SN2007):Section F: Construction except group 41.1, Development of building projects. The observation unit is enterprises, but before 2016 local Kind of Activity Unit (local KAU) data was collected.

Information from enterprises through a quarterly survey and data on employment from the Central Register of Establishments and Enterprises.

The sample includes all the enterprises employing 20 persons or more, about 2 200 units. These enterprises cover about 30 percent of the employment in the construction industry.

The data is collected by electronic survey at the end of the quarter, and the questionnaire can be filled out by Statistics Norway on Internet at Altinn, Altinn.no.

Mathematical and logical controls are incorporated in the registration procedure to verify the consistency in the values stated on the form and the correspondence with reserve values given the previous quarter. If a discrepancy is discovered, the respondent is contacted by phone or e-mail.

Indices are calculated by comparing new orders and stock of orders for enterprises included in the sample both in the basis quarter and in the statistical quarter in question. The data from the sample enterprises are not grossed up to the population. It is assumed that the development in the sample is representative to the development in the whole population.

The index is published as a value index with the year 2010 as reference period.

The calculations can be described by the following equation:

where

U _t = all enterprises in the sample giving data in quarter t .

O _t = the value of new orders or the value of stock of orders in quarter t.

O _o = the value of new orders or the value of stock of orders in quarter o .

The sample is updated every first quarter of a year. The index figures are chained with the first quarter as new basis.

Seasonally adjusted series are available for stock of orders for civil engineering, construction total and residential buildings. The numbers are adjusted for seasonal variations applying the X12ARIMA method with non-fixed seasonal effects and multiplicative model. No pre-correction of trading-day or Easter effects. Trend data are computed for all series.
